The portable accessory lighting device 50 includes three articulating and reconfigurable support legs 100 which serve as the supporting portion 56 of lighting device 50 to serve as a stand, a twist or wrap support or other supporting structure. One of the reconfigurable support legs 100 is illustrated in FIG. 7 having a plurality of interconnected segments 110 serially connected via links 112 in a manner to allow flexure and reconfiguration of the leg 100 about multiple axes. Segments 110 may be made of rubber and may have a shape of a disc, according to one embodiment, having a recessed opening or socket 116 at opposite ends for receiving an enlarged spherical head 114 of link 112 to form a ball and socket connection between adjoining link 112 and segment 110. Each link 112 has a central shaft with enlarged spherical heads 114 at opposite ends and may be made of a polymeric material or plastic. The enlarged spherical head 114 is trapped within socket 116 and is movable relative to segments 110 when sufficient force is applied by a user to reconfigure the shape of the leg 100. As such, adjacent links 112 are able to rotate and pivot in multiple axes relative to the ball and socket connection. Each leg 100 may be articulated and twisted by a user in various directions and be rotated to form a user reconfigured shape that is desired to support the accessory lighting device 50 in various orientations. The reconfigurable legs 100 may therefore provide a freestanding support for lighting device 50 or may engage and wrap around members and retain the accessory lighting device 50 in a desired orientation and position.
In one embodiment, the rubber segments 110 are flexible and may bend independent of the pivoting ball and socket connection formed with the links 112. The links 112 may be rigid, according to one embodiment. According to other embodiments, the links 112 may be made of a flexible material that may flex independent of the ball and socket connection and the segments 110 may be made of a rigid material. The ball and socket connection between segments 110 and links 112 allows for rotation of segments 110 relative to links 112 about the longitudinal axis and rotation in other axes. Each segment 110 and interconnecting link 112 allows for relative motion therebetween to allow for various configurations of the reconfigurable legs 100. In addition, the uppermost enlarged spherical head of link 112 serves as a tripod pivot connector 102 that is adapted to connect to a tripod stand to support the leg 100 relative to the other legs 100 and may include various shapes and sizes for allowing articulating motion of each leg 100.
The articulating legs 100 are easily reconfigured to various configurations. The reconfigurable legs 100 may be aligned substantially straight and parallel to one another in an unexpanded arrangement as shown in FIG. 6 for easy insertion and installation in the housing 22. With the reconfigurable legs 100 in the unexpanded configuration, the three reconfigurable legs 100 may also serve as a handle for removing the lighting device 50 from housing 22 and transporting the lighting device 50 for portable applications. A user may pivot the reconfigurable legs 100 relative to one another to form a tripod and may shape each individual leg to achieve a desired orientation of the lighting device 50. In addition, each leg 100 may be bent to wrap around an object and the suction cups 120 may be suctioned to a flat surface, such as a window. It should be appreciated that various other applications of the portable accessory lighting device 50 may be realized.
Referring to FIG. 8, the accessory lighting device 50 is further illustrated. Head portion 52 is shown having a rear support bezel 60 for receiving a circuit board 62 having three lighting sources 64 shown as three light emitting diodes (LEDs) mounted thereon. A cover plate 66 having three windows 68 is disposed in front of the circuit board 62 such that the openings 64 are aligned with the light sources 64 to allow output light to penetrate therethrough.

In addition, a push actuated switch 76 is shown disposed on circuit board 62 and has a portion that extends through circuit board 62 and contacts cover plate 66. Depression of the lens 70 causes cover plate 66 to forcibly activate the switch 76 to turn the lighting device 50 on and off, with each repeated depression of the lens 70 causing switch 76 to switch on and off states. A user may turn the accessory lighting device 50 on by pushing on the lens 70 and off by repeatedly depressing the lens 70.
The head portion 52 of lighting device 50 is connected to base portion 54 which has a housing 80 adapted to be fastened to support bezel 60. Housing 80 has a compartment for receiving a battery receptacle 84 with positive and negative contacts 86 and 88 which are adapted to receive a rechargeable battery 90. Electrical circuitry is included to supply electrical power from the battery 90 to the light sources 64 when switch 76 is activated. The battery compartment 84 has electrical circuitry connected to electrical contacts 82 which allows for the rechargeable battery 90 to be charged when electrical contact is made with the spring biased contacts 48 within the housing 22. The rechargeable battery 90 may supply DC voltage and charging circuitry may be included in the vehicle 10, the light assembly housing 22 or the lighting device 50.
The supporting portion of the accessory lighting device 50 is shown having three flexible articulating and reconfigurable legs 100. Each of the three reconfigurable legs 100 has a tripod pivot connector 102 at the top end thereof configured to be received within any opening or socket 104 in tripod support member 106. As such, the ball and socket connection between each tripod pivot connector 102 and socket 104 allows each of the three supporting legs 100 to articulate by pivoting and rotating in various directions. A plate 92 is disposed over member 106. Legs 100 further have suction cups 120 formed on the bottom ends thereof to allow for suctioned coupling to a smooth surface such as a window. It should be appreciated that each of the legs 100 may be self-supported and yet is reconfigurable to be adjusted into various orientations to position the accessory light device 50 as desired by a user.
